Cortical inflation and maintenance of surface voxel intensity
by Assis Lopes, Pedro Augusto 21 Jan '20

21 Jan '20

Dear Freesurfer experts, I am a medical student and am currently doing a fellowship at the JPK Stroke Research Center - MGH. My current research project involves measuring the area of a cortical hypointense brain MRI signal (cortical superficial siderosis) , a marker that lays along the subarachnoid space/pial surface, only visible in blood sensitive MRI (SWI in my case). In summary: We are trying to do a parallel to fMRI studies (fMRI x T1w // SWI x T1w), analyzing SWI signal intensity on a registered inflated brain surface; Projecting SWI surface intensity would then allow manual area demarcation of hipointensities in a flat surface. Here is our step-by-step plan (analogous to fMRIxT1w registration/BOLD signal intensity projection to surface): 1. Perform freesurfer recon-all of the subject in question to generate subject-surface models. 2. BET and register the image of interest (SWI) into the freesurfer-subject space (register both SWI and MEMPRAGE sequences) [bbregister] 3. Having SWI in subject space and a surface model (generated in 1); * Split registered SWI into LH and RH * Tkregister2 to get LTA to mri_vol2surf format * Mri_vol2surf each hemisphere to the recon output 4. Display the SWI hemi surface as an overlay 5. Inflate T1 surface and observe its SWI overlay; * Manual demarcation of characteristic SWI hypointense signals 6. Analyze measured signal We did try this approach, but yet with these steps we could only obtain an inflated cortical surface representation that has no correspondence to SWI`s intensity. So, here comes the question: If BOLD signal intensity can be projected onto surface area; is there a way to project SWI intensity onto the cortical surface? Or Can we preserve the info of SWI surface voxel intensity while doing the surface inflation? If not Is it possible to use the positional information of t1w voxel (used in inflation process) as an index to retrieve its correspondent SWI intensity value? Sorry for the long question. In advance I thank you already for being so attentive. Best, Pedro Pedro Augusto Assis Lopes Student Researcher J.

Freeview Surface Loading View Center
by Mingjian He 21 Jan '20

21 Jan '20

Hi, When using Freeview to load a surface file without volume, how does Freeview set the initial view center and cursor position? I’ve checked mid point of xyz ranges, centroid of vertices, and median. None of these gives me the initial SurfaceRAS values when opening the surface with Freeview. Thank you!

Input PET images for PetSurfer Analysis
by Ferraro, Pilar 21 Jan '20

21 Jan '20

External Email - Use Caution Dear Freesurfer experts, I am starting a new analysis using PetSurfer to evaluate the effect of different PVC corrections on brain metabolism in a set of patients. I have already analyzed all the T1 MRI data using the normal stream, however I have never worked on PET data before. I have the original DICOMS from a static PET acquisition but I’d like to know more about the preprocessing steps needed for these PET data. I am thinking I should simply convert PET DICOMS to NifTI, normalize them to a standard template and then smooth them with 8- mm full width at half maximum Gaussian Kernel to obtain the input images for the PetSurfer analysis. Am I correct or should I add further preprocessing steps?

The second project had two groups with three co-variates looking at psychiatric x BMI interaction effect on brain volume. I'm interested in running ROI analyses in matlab to ensure the same matrices were used. To run the ROI analyses I'm going to important the design matrix from the vertex wise analysis and use the fast_glmfit and fast_fratio commands as shown below: X = load('Xg.dat'); C = load('C.dat'); y = load('ROI.dat'); text file containing participant ROI values from the DKT atlas. [beta rvar] = fast_glmfit(y,X); [F pvalues] = fast_fratio(beta,X,rvar,C My first question is the beta values that are calculated from fast_glmfit are unstandardized is there anyway way to have it compute standardized values? My second question is when I ran the ROI analyses looking at the diagnosis x BMI interaction effect it outputs an array of beta values for each regressor. In addition to each groups beta value (for BMI) I'm interested in the beta value of the interaction (ie diagnosis x BMI). I was wondering how do i go about obtaining this? Would I have to create a new matrix with the interaction term included in it? If so would the analysis essentially be one group with the diagnosis x BMI interaction term plus the three co-variates? -------------- next part -------------- An HTML attachment was scrubbed...

Change the subject ID after recon-all?
by Tim Schäfer 21 Jan '20

21 Jan '20

External Email - Use Caution Dear FreeSurfer experts, I have two questions on subject IDs in FreeSurfer output. 1) is it possible to change to subject identifier in the FreeSurfer output after recon-all has been run? Background: I would like to upload data pre-processed with FreeSurfer to a consortium server. The subject ID is a random identifier, but the upload guidelines say this identifier must only occur in certain file types (Excel files, .log files, and some more, but not in any other files). I noticed that a lot of the output files produced by FreeSurfer contain the subject identifier somewhere, including various binary files, so I guess there is no easy way to change it. But maybe there is? Like rerunning a part of recon-all? 2) If not, I could rename the source NIFTI files (e.g., from the identifiers to something like 'subject001', 'subject002', ...) and re-process everything. This would take some computational time for the > 500 subjects, but it would be okay I guess. But a large number of the subjects have manual edits applied already. Is there a way to keep the manual edits? E.g., I thought maybe I could rename the individual directories of the edited subjects, leave the edited files in there, and run recon-all again. But what would happen? Will the new output files have the renamed ID from the directory name (and thus the recon-all command line), or will they still use the old ID (from the header of the existing files)? Or will the existing, edited files which contain a different ID be ignored during the new run because the IDs do not match, and thus the existing edits would have no effect?

Hi everyone, This is a reminder that registration for the Spring 2020 FreeSurfer course will open TOMORROW (Tuesday, January 21st) at 10:30am EST! At that time, the link to the registration page will appear on the course website: https://surfer.nmr.mgh.harvard.edu/fswiki/CourseDescription The four-day course will run from March 30th through April 2nd, 2020 at the Massachusetts General Hospital Martinos Center for Biomedical Imaging in Charlestown, Massachusetts. The schedule for this course has not been finalized but an example schedule can be found on the course website: https://surfer.nmr.mgh.harvard.edu/fswiki/CourseDescription How to get a spot in the course -Easy! Register on the day we open registration & submit an accepted form of payment by the deadline. Some reasons why people are unable to attend the course: -Waiting too long to register. The 50 seats in the course usually fill up within a day or two. -Waiting too long before requesting a check from their institution. (Make sure you put in the request for a check immediately *after* you register.) -Not realizing cash payments must also be made by the deadline. (MoneyGram or Western Union transfers are accepted as well as personal deliveries.) -Booking flights, sending in payment, and/or just showing up without registering for the course or moving up from the waiting list! For questions about the course, you'll likely find answers on the course website. If you don't find what you're looking for, feel free to email the course organizers at freesurferlab(a)gmail.com. If you would like to hear about future course dates, sign up for the course mailing list here<http://surfer.nmr.mgh.harvard.edu/cgi-bin/fsurfer/interest.cgi>. ------------------ FreeSurfer Course Organizers Massachusetts General Hospital Athinoula A.
